Abstract: An extended version of antisymmetrized molecular dynamics was developed to study the structure of p-sd shell hypernuclei. By using an effective ΛN interaction, we investigated the energy curves of 9ΛBe, 13ΛC, and 20,21ΛNe as a function of nuclear quadrupole deformation. The changes to nuclear deformation caused by Λ particles are discussed. We found that Λ in the p wave enhances nuclear deformation, while that in the s wave reduces it. This effect is most prominent in 13ΛC. The possibility of parity inversion in 20ΛNe is also examined.
